So I'm installing the new American autowire update kit. Where would be a good location for the main 175amp fuse that comes with the kit? Was thinking of putting it where the old horn relay would be on the fender. If anyone has done this kit where did you put it? Thanks

 

Where does the kits wiring diagram show to hook it up? You have 2 175A fuses bussed together.

 

 

That looks to be a good set up. Does the new kit do away with the horn relay? If it is still used then then mount it near the relay, you need to run a jumper to it from one of the 2 fuses. If not mount it in its place.

 

No it has an updated relay under the dash so the one on the fender is not used. That's where I think I'm going to put it as long as it dont interfere with hood or something else. Thanks

 

Why take it down to the starter when it can be connected directly to the battery post? I'd rather not run a second main wire near the exhaust if I didn't have to, especially if I have headers.

 

I would assume it's to protect rest of the system, more like newer cars have? Second wire coming off of starter is a smaller 6 gauge wire. I am putting heat resistant covering on wires around header.

 

I don't think so because it would just be a stacked connection with both cables on the main post. That is another reason I don't like the idea of running the wire to the starter.

 

The drawing posted up top is a good wiring set up and will probably work fine. Randy is correct the least amount of connections at the starter is better, its also easier and safer if the power wire goes directly to the battery. You don't have to worry about heat or the wire accidentally shorting out to the exhaust or something.

 

I would invest in some terminal covers to prevent accidental electrical shorts. Here's some I've used in my project. These fit 1/4"- 5/16" studs, check the size of the on the fuse blocks to make sure these will fit.

 

The fuse block has a cover with it, I just didn't picture it. Those are pretty cool though. Thanks

 

Mount it to the inner wheelhouse, in the area in front of the tire. It’s near the battery, it will be well protected simply due to its location, and will be pretty close to to the alternator and firewall bulkhead connector.

if your running headers, I’d strongly consider going one step further with your wiring upgrades. Use a Ford starter solenoid. That way there are no cables that are powered unless your cranking the engine. If you can’t stand the thought of brand “X” parts on your Olds, use lots of insulated cable clamps to make sure the battery cable is routed far from the headers, and stays that way.
